Zinc tabs work for me; I take them on flights and they seem to work pretty well. Prayers for your healing. (((HUGS)))!!! Oh, and hit some melatonin for sleep aid - it’s a natural secretion of the brain so it’s natural. I’ll hit 20mg’s to get me to sleep on trips.
I’ve had luck with Zicam before, and have been using it since Sunday, but there seem to be too many “germans” for it to get them all.
